Four flap enclosures are a safe, effective method to store documents and pamphlets without boxing or attaching them to a case. The enclosure fully protects and securely holds your material so it can be easily shelved. The precision die cut 10 point inner four flap with a single spine score is attached to a 40 point outer folder with a green poly-cotton C grade cloth spine that allows easy labeling. Both are made of sandstone archival board. Available in a variety of sizes, the four flap enclosure safely covers your important documents for long-term protection.

These heavy-duty four flaps allow insertion and removal without damage. The acid-free, lignin-free board gives long-term protection and is available in standard sizes in 10 point sandstone archival board with a 1/8 inch spine score for thin items or in 20 point sandstone archival board with multiple spine scores for items 1/4 to 1 inch thick (see Adjustable Four Flap Enclosure).
